An alloy of Nd(10-x)Fe81.2B8Cu0.8Wx was produced by mechanical alloying.and its structure and magnetic properties were studied.Using X-ray diffraction(XRD),scanning electron microscopy(SEM) and vibrating sample magnetometer(VSM),samples of different milling time,the microstructure morphology and the magnetic energy.The results showed that The right amount of W addition can promote the precipitation of hard phase Nd2Fe14B and improve the oxidation resistance of the magnet.The sample has the best magnetic properties with the 1% wt of W addition.
